Where do you get " nasty vocabulary and bad attitude " from ? Merriam-Webster defines ignorant as; lacking knowledge or comprehension of the thing specified. If I called people stupid morons I would understand, but like I said, I too believed the FAA and the manufacturers at 1st until I came across things that were not correct. And I only new this because of my vast experience in auto and motorcycle racing and the physics of engineering that I had been taught. I don't know John at Sac Sky Ranch, so I don't know what he experienced. But I do know a pilot that has been racing at Reno in the Formula 1 class for a long time that still uses, and has cases of that old mobil one aviation oil that they stopped selling in 1994, and he spins that 0-200 well over 4,000 RPM, and he hasn't had the problems other racers experienced using other aviation oils. I use Mobil 1 car oil and I buy 5 qt jugs for $26 at Walmart. I am just trying to help out fellow pilots with scientific knowledge that for whatever reason is suppressed or ridiculed in the aviation community. And a few of the people in this forum are not the 1st to charge me with Heresy going agsinst the Religion of certified aviation. For over 10 years I've shown people the pistons and let them look inside the lower end of my 0-200 that hasn't been apart since 1975, yet looks brand new like it was assembled yesterday, and they still won't believe. But fortunately there are people that are new to aviation that are not disciples of this strange religion that do believe in facts and science.
